1
Stand with feet shoulder-width apart, knees slightly bent, core engaged, and arms at sides holding dumbbells with neutral grip (palms facing inward) and elbows close to torso
2
Maintain neutral spine and shoulder-back position with dumbbells held at thigh level, ensuring elbows remain stationary against the ribcage throughout the movement
3
Lower the dumbbells in a controlled manner by allowing the elbows to extend, moving the dumbbells down to starting position while maintaining tension in the biceps and keeping elbows stationary
4
Curl the dumbbells upward by flexing the elbows and contracting the biceps, rotating the wrists to supinate the forearms at the top of the movement until dumbbells are at shoulder height, then reverse to lower position
